This does not set a mood and thus does not convey the same information. This removes the information about mood and setting away while keeping only rough plot point in.
The outcome in terms of how reader interpret the situation is massively different. The thing you wrote implies that all they need is to go to sleep an hour sooner and rest, all will be fine.
The thing you're describing that's missing is context, not information. At that point in the plot, the reasons why they couldn't simply take a break wherever they wanted had already been explained, so it didn't need restating. As for mood-setting, I've already addressed that in other replies.
